I think this trimmer is best product from nova, price is very low and the priduct is best. This is a wireless trimmer , very smoth for trim beard. I am using since 6 month. The battery backup of this trimmer very good it last around 40 minutes. The trimmer comes with 1mm, 6mn and 9mm adjustment by which you can cut your hair also. Nothing is maintanance , just charge 1 hour before using. You will get cleaning kit also, like oil, smal brush. After using just remove dust with brush and keep. It cost only Rs 270 when I bought, and 6 month happen its still running well.
